针对主流单阶段实例分割算法因冗余语义信息造成实例掩码缺失和泄漏的问题，提出一个基于语义对齐和图节点交互的实例分割算法。在全局掩码生成阶段，设计一个语义对齐模块，通过全局映射和高斯映射评估语义信息对全局和局部语义完整性的影响，从而对冗余语义信息进行抑制。此外，在实例掩码组装阶段，设计一个图节点交互模块。该模块通过对特征图进行图结构数据变换和图节点信息交互，提取拓扑图的空间特征，补充了掩码组装信息，进一步提高了实例掩码的准确度。实验结果表明，所提算法在MS COCO数据集上实现了38.3%的平均精度均值（mAP），与其他先进算法相比，有很强的竞争力。

This Letter is concerned with the influence of polarization on the damage performance of type I doubler potassium dihydrogen phosphate crystals grown by the conventional growth method under 532 nm pulse irradiation. Pinpoint density (ppd) and the size distribution of pinpoints are extracted through light scattering pictures captured by microscope. The results show that the ppd of polarization that parallels the extraordinary axis is around 1.5× less than that of polarization that parallels the ordinary axis under the same fluence, although polarization has no influence on size distribution of pinpoints. We also find that the size distribution is independent of fluence, although the number of pinpoints grows with fluence.
